bald tail tip?

Didn't want to hyjack to the other post, but Gailann, you said something about tail tip being bald...is this an indication of deficiency? I hadn't really thought of it but our buck who has been the subject of much discussion has an oddly bald tail tip.....

I'd agree with this being a copper deficiency also. I've had this happen with bucks that we've purchased. We give copper bolus to all our guys and they have access to minerals with copper in them also. In addition to the bald tail, (which was our first indication) look for rings around the eyes.
